Boss DSD-2 Digital Sampler Delay New
« on: September 13, 2018, 06:27:11 PM »
Regarding this Boss DSD-2 Digital Delay pedal schematic:



It seems the DAC (RA1) out goes through a buffer (6), through some analog gates (4abcd) and out. But it also goes down to the comparator (5) which is being used as an ADC? Why is the output mixing with the input?

I have another piece of gear I'm trying to fix (see other thead in The Lab) that uses the same chip (RDD63H101) so I'm just trying to understand how this works.
